Welcome to the Linux Weather Forecast
This page is an attempt to track ongoing developments in the Linux development community that have a good chance of appearing in a mainline kernel and/or major distributions sometime in the near future. Your "chief meteorologist" is Jonathan Corbet, Executive...

The recently revealed Meltdown and Spectre bugs are not just extraordinary issues of security, but also performance. The patches that workaround Meltdown introduce the largest kernel performance regressions I've ever seen. Many thanks to the engineers working hard to develop workarounds to these...

The Linux Foundation is pleased to welcome LinuxBoot to our family of open source projects and to support the growth of the project community. LinuxBoot looks to improve system boot performance and reliability by replacing some firmware functionality with a Linux kernel and runtime...

Spectre and Meltdown are major design flaws in modern CPUs. While they're present in almost all recent processors, because Intel chips are so widely used, Intel is taking most of the heat for these bugs. Nowhere has the criticism been hotter than on the Linux Kernel Mailing List (LKML). That's...

A kernel that has had nearly 83,000 patches applied will certainly have a few bugs introduced along with the new features, states the 2017 Linux Kernel Development Report, written by Jonathan Corbet and Greg Kroah-Hartman.
To find and report those bugs, Linux kernel developers depend on a wide...

In an almost unprecedented move, Linus Torvalds has delayed the release of a final build of the Linux Kernel 4.15, instead announcing an unusual ninth release candidate, the first time he had felt he has to do so since 2011.
And you can be fairly sure that Torvalds is not happy with the release...

If your Linux systems are running a normal Linux distribution, go update your kernel. They should all have the updates in them already. And then keep updating them over the next few weeks, we are still working out lots of corner case bugs given that the testing involved here is complex given the...

So, where are we with fixing the problems? Work is continuing, but the latest update of the stable Linux kernel, 4.14.2, has the current patches. Some people may experience boot problems with this release, but 4.14.13 will be out in a few days.
Patches have also been added to the 4.4 and 4.9 stable...

Linux kernel 4.15 has been in development since the end of November 2017, and it's now time the development cycle to come to an end, and today's Release Candidate brings even more of the x86 page table isolation (PTI) patches to mitigate those nasty Meltdown and Spectre security vulnerabilities...

A serious security memory problem in all Intel chips has led to Linux's developers resetting how to deal with memory. The result will be a more secure, but -- as Linux creator Linus Torvalds says -- slower operating system.
Long ago, Intel made a design mistake in its 64-bit chips -- and now, all...
